A pin is provided, necessary to rotate this rod many times in which pin is adapted to pass through the hol order to cause a large adjustment 0f the jaws, and likewise this threaded rod must be made of excessive length, thus increasing the cost of the device. the By my invention, I provide one adjuste,
